Republicans and reality dominated television last night. Vice-Presidential nominee Paul Ryan was the star speaker at the Republican National Convention on Wednesday and, as they had on Tuesday, ABC, NBC and CBS all aired an hour of the convention live from Tampa, Florida.  NBC won the ratings vote, with a 1.3/4. For the second night in a row, the network also pulled in the most total viewers to its convention coverage with 4.517 million watching. The coverage that both NBC and CBS, who got a 0.6/2 rating and 2.840 million total viewers, had last night could not be compared to that they gave the GOP convention on the comparative night back in 2008 because that coverage ran without commercials and was sustained by Nielsen. With a 0.7/2 rating and 2.602 million viewers total, ABC, who did run commercials four years ago, saw its coverage free fall 61% from the comparative September 3 night at the 2008 GOP Convention.  NBC won the night among Adults 18-49 and, with 6.485 million watching, total viewers. With the live convention coverage, as well as local football pre-emptions in some markets on ABC, CBS and NBC and weather coverage down in the Gulf Coast area, Tuesday’s Fast Affiliate Ratings are likely to change later today.

On CBS, Big Brother (2.3/7) was up 10% from last week. With 6.71 million total viewers, the multi-night reality series hit a Wednesday night viewer high last night. America’s Got Talent (2.5/7) had its first semifinal results show of this season. The NBC competition series saw three contestants go through to the finals and a 9% rise from last week’s show. With 9.130 million total viewers, the new America’s Got Talent was the most watched show on TV last night. The CW’s Oh Sit! (0.4/1) was even with last week’s rating. On Fox, two more contestants were eliminated on So You Think You Can Dance (1.6/5), bringing the field down to six. The two-hour live show last night got some lift in its step, SYTYCD was up 7% from last week. Otherwise it was a patch quilt of repeats across the other networks.  NBC had an America’s Got Talent (1.4/5) encore at 8 PM and CBS had a Criminal Minds (1.3/4) repeat at 9 PM. Besides the GOP Convention, ABC went for a night of repeats with The Middle (1.0/3), Suburgatory (1.1/3), Ann Romney’s favorite show Modern Family (1.3/4) and another Suburgatory (1.1/3) at 9:30 PM.
